Please, if someone sends me a MAC Indesign file with links in it that I can't open because they are just links to some other original files, like graphics or whatever, when I send the file back, will the llnks get back into place with their source files when they are back on the computer where the originals are filed, and will the user at the other end be able to see them? Even if my computer is a PC and theirs a Mac?
